Phytoplankton distribution and abundance data collected during the RV Investigator research voyage IN2021_V01 from 29 January to 24 March 2021. The voyage, part of the TEMPO survey, sailed from Hobart to Hobart to estimate Antarctic krill biomass. Data were collected along six north–south transects spanning 55°E to 80°E, extending from approximately 62–63°S to the sea-ice edge.
Use Cases
- Modeling krill habitat suitability based on phytoplankton abundance as a primary food source mentioned in the description
- Analyzing spatial patterns of phytoplankton distribution along six north-south transects spanning 55°E to 80°E
- Comparing ecosystem conditions over time by leveraging overlap with transects from the 2006 BROKE-West voyage
- Supporting updates to precautionary catch limits for Antarctic krill within CCAMLR Division 58.4.2-East
Strengths
- Data collection spanned a defined period from 29 January to 24 March 2021
- Spatial coverage includes six transects from 55°E to 80°E and from approximately 62–63°S to the sea-ice edge
- Enables temporal comparison as several transects overlapped with the 2006 BROKE-West survey lines
Limitations
- Column-level documentation is absent; field semantics must be inferred after download
- Row count is unknown, which may limit suitability assessment
- Description metadata is limited; actual data quality requires manual inspection after download
